feat(core-architecture): consolidate dependencies, Swagger docs, and cache - #4

Wires all four packages' providers and commands into adonisrc.ts, and
registers the bouncer initialization middleware in start/kernel.ts, so
the IoC container can resolve ctx.bouncer, the mail service and the
cache service anywhere in the app.

Generated by the package's own configure command. The Edge template
sharing branch in the middleware is removed since this project has no
view provider, API only per the README's architecture. The
policies.ts registry is empty for now, no policy classes exist yet.

Database store over Redis, matching this project's pattern of reusing
the one shared PostgreSQL instance instead of adding a second piece of
infrastructure. The default is hardcoded to 'database' rather than
read from LIMITER_STORE, since 'redis' is a documented but unconfigured
env value with no matching store here. A global throttle stub is
defined in start/limiter.ts for feature/auth to point at the real auth
routes.

SMTP is the only transport this project needs. The generated globals
block for Edge template variables is removed, this project has no
view provider and mail bodies are built as plain strings in the mailer
classes that later branches add.

Same reasoning as the limiter: the database driver reuses the existing
pg connection instead of adding Redis. Most reads never touch the
database at all since the memory layer sits in front of it; the
README names the categories list as a candidate for this once that
branch exists.

/swagger returns the generated OpenAPI spec, /docs renders it through
Swagger UI, both public. tagIndex is set to 3 to match this project's
/api/v1/<resource> route convention, and authMiddlewares points at the
auth named middleware so protected routes are flagged with the bearer
token security scheme automatically.

…y, validate mail vars

APP_KEY was weakened from Env.schema.secret() to string() when this
file first added the auth, database and hashing env variables, losing
log redaction for the key backing session and cookie encryption.
Fixed at the source. JWT_SECRET gets the same protection since it
signs every issued token. Mail variables are validated the same way
every other env var in this project is.

Adds the SMTP_HOST/SMTP_PORT/MAIL_* section to all three env files,
pointed at the Mailhog service docker-compose.yml and
docker-compose.test.yml now run, ports 1025 and 1026 respectively.

Catches every outgoing email instead of attempting real delivery.
Test stack uses offset ports (1026/8026) so both compose files can run
side by side, the same reasoning docker-compose.test.yml already
applies to its postgres service.

Needed once a later branch sends real email in a functional test.

Both auto-generated, refreshed to reflect the new routes and the
rate_limits/cache tables. Neither is hand edited.

The Tasks list now names every package the whole project's Tech Stack
table needs, installed once here instead of one at a time as later
branches reach the point of needing them. Bouncer, limiter and mail
get their base scaffolding here too; the app-specific wiring each one
needs (the JWT guard, Argon2 as the active hasher, real policies)
still belongs to the branch whose behavior it is.

Reconciles feature/core-architecture (recreated from its original tip
and extended with the full dependency and configuration consolidation
requested mid-session) with everything data-modeling and auth already
built on top of the original scaffold.

Conflicts resolved in favor of develop's already-working versions
wherever both branches touched the same concern: the real env-driven
authThrottle over the generic limiter stub, the TEST_ADMIN_EMAIL block
in start/env.ts, and the auth-schema rate_limits migration over the
duplicate one this branch generated independently, which is removed
here rather than kept alongside it. Genuinely new pieces are additive:
adonis-autoswagger with /swagger and /docs, @adonisjs/cache with a
database backed L2 layer, and the APP_KEY/JWT_SECRET Secret redaction
fix applied at its actual source commit.

Verified against a live PostgreSQL and Mailhog instance after
resolution: migrations run cleanly to 14 tables, seeders complete, and
the full test suite passes 41 of 41.
